Means or PROPULSION.

Specification of Letters Patent.

Patented Aug. $2, 1911..

Application filed August 30, 1910. Serial No. 579,689.

T 0 all whom it may concern:

Be it known that I, VINCENT C. on YEAR- nonno, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Means of Propulsion, of which the following is a specification.

This invention has for its object to pro vide improvements in means of propulsion, more particularly related to flying machines and other mechanism and apparatus for navigating the air, which will be superior in point of degree and facility to control, positiveness in operation, relative lightness and simplicity of construction, and adaptability to varying conditions incident to use and service; and which will be generally superior in point of efficiency and serv iceability.

With the above and other objects in use, the invention consists in the novel provision, construction, formation, combination and association of parts, members and features, all as hereinafter described, shown in the drawing, and finally pointed out in claims.

The present invention was originally dcscribed, disclosed and claimed, in a parent application for patent for air ships, filed by me January 11, 1910, Serial No. 537,546.

in the drawing z-Tigure 1 is a frag mentary top plan view of a flyin machine provided with means of propu sion embodying the invention; Fig. 2 is a side elevation of the same, partly in longitudinal section for clearness of illustration, the section being taken upon the line a-a Fig. 1; Fig. 3 is an enlarged vertical transverse sectional view taken 11 on the line b-b, Fig. 2, parts being bro en away for clearness of illustration; and, llig. is a frag mentary plan view of a portion of the construction at the right hand end of Figs. 1 and 2, the same being upon an enlarged scale and being part1 in section for clearness of illustration. both ofthe sectional views above specified, the line of vision is in the direction of the appended arrows.

Corresponding parts in all the figures are designated by the same reference characters.

Referring with particularity to the drawings, A? designates a portion'of the main supporting plane of a flying machine, of the monoplane type, from which is s spended a deck 3 upon which motive means E are mounted, the same operating the propeller O which is an element'of the means of propulsion constituting the invention. All of the parts are connected together and braced by suitable frame members 5, the form and arrangement and connection of which is not concerned in the invention.

In the drawing various incidental features of flying machine construction are shown, malnly fragmentary, and these are also not concerned in the invention.

0 designates the controlling means for the propeller C.

The propeller G is so mounted that the same may be deflected from its normal po sition in which it acts to cause direct 1ongitudinal movement of the flying machine, into downwardly, upwardly, and oppositely laterally facing "positions in which it may act to depress or elevate the forward end" of the flying machine, or to deflect the lat ter laterally in either direction from a straight-away course; all as determined the agency of the control means a; and the same comprises an annulus or wheel 6 from the forward face of which projects a semicircular frame 7, the central portion of which is formed into a mounting 8 for the shaft 9 of the propeller C. The annulus G is rotatively mounted within an outer annulus 10, a ball race being provided between the two annuli as'clearly shown in Fig. 41: at 11. The outer annulus is providcd with oppositely projecting elongated bearings, 12 and 13, respectively. The inner annulus '6 is provided with diametrically opposed heads 14, which receive loosely opposed projecting stub-shafts 15 upon a ball 16 with opposed portions of the surface of which the heads 14 loosely engage so as to be capable of rotation upon the stub-shafts 15. The forward end of the main plane A is provided with a bearing 16 which receives rotatably two interior locking clutch members, 17 and 18, respectively, the clutchmember 18 being connected with or formed upon a power shaft 19 extended from and actuated by the motive means E. A collar 20 locked to the shaft 19 limits forward longitudinal movement of the clutch member 18. The clutch member 17, entering the bearin 16 from the oppositeend, carries at its forward end a fixed yoke 21, the armsof which receive rotatahly the respective end portions of bearings 22 projecting oppositely from theball 16 and rectangularly with respect to the stub-shafts 15. The power shaft 19 extends rearwardly of the main frame of the machine through a suit-able bearing 23 and is directly con- 'ected with a motor E which may be of ,the hydro-carbon explosive type or of any other suitable nature.

- The elongated .bearing .13 of the outer annulus 10 is received. at its outer end with- ,in a segmental keeper 24 forwardly of the forward end of the frame; said outer end of said bearing having a suitably flanged sleeve 25 acting as a bearing within the keeper 24. Outwardly of the keeper 24 a collar 26 is loosely applied to the bearing 13. A connecting rod 27 extends from a yoke 28 which is loosely'pivotally connected with the outer end of'the bearin 13, rearwardly to a crank arm 29 the sha of which is provided with a lever arm 30 pivotally =m'ounted upon the frame; said lever arm carrying a dog 31 which co-acts with a toothed sector 32 mounted upon the frame, to constitute a well-known form of operating and controlling means. Oscillation of the lever arm 30 causeslongitudinal movement of the connecting rod 27 to move the sleeved end of the bearing 13 within the segmental keeper 24, and causes the propeller C to face laterally of the longitudinal medial axis of the main frame or of the ma- 'chine. The swinging movement of the bearing 13 last described, which carries with it in such movement the annuli 6 and 10; and

the bearing 12, together with the mounting 8 of the propeller shaft, is permitted by the pivotal mounting of the bearing 12 upon a bracket 33, arranged forwardly from the main frame; the outer end of the bearing '12 being surrounded by a sleeve34 having vs'pllt' ends pivotally connected with the bracket 33, as at'35. The outer end of'the bearing 12 is provided with a crank arm 36 from which extends rearwardly a connect- 1ng rod 37 ivotally connected at its rear- I ward end Wlt. a crank arm 38 the shaft of whlch is supported upon a frame member and is provided with a lever arm 39 provided with a dog 40 which co-acts with toothed sector. 41. Oscillation of the lever arm 39 causes the crank arm 36 to rock,

between, whereby the thrust area of the propeller is largely increased, although its total working zone is slightly greater than that necessary for the operation of a propeller having one-part or unitary blades. The propeller isset to operate in such manner as to expend the power generated thereby in traction upon the machine.

, The operation, method of use and advan-' tages of the improved means of propulsion constituting the invention will be readily understood fromthe fore oing description taken in connection with the accompanying drawing and the following statement: Through the control means cthe propeller C may face to predetermined degrees upwardly, downwardly or laterally 1n either direction; and either upward or downward adjustment may be combined with either lateral adjustment for resultant adjustment composite of both manipulations. In adjust-ing the propeller C tocause the same to face upwardly or. downwardly, the bearing 12, together-with the bearing 13 and the intermediate parts and features, is rocked through the agency of the crank arm 36, the connectin' rod 37 and the lever arm 39'. Lateral acing of the propeller C in either direction is caused through the agency of the connecting rod 27 and the le ver arm 30. In whatever plane of rotation the propeller may be located, such rotation is caused bythe-rotation of thepo'wer shaft 19 which in turn rotates the clutch members 17, and 18, the yoke 21, the ball 16 and the heads 14, which receive the bearings 15 upon the ball 16; the mountin 8 for the fixed shaft 9 of the propeller heing thereby rotated; and the said rotation takes place as between the annulus 6 and the annulus 1.0,

which are separated by the ball race'll.

I do not desire to be understood as limiting myself to the specific provision, construction, formation, combination and relative arrangement of parts, members and features shown and described; but reserve the right to vary the same, in adapting'the'improvements to varying conditions of use, without departing'from the spirit of the invention and the terms of the following claims:
